Lineage for d1j5qb2 (1j5q B:222-437)

Fold b.121: Nucleoplasmin-like/VP (viral coat and capsid proteins) [88632] (7 superfamilies)sandwich; 8 strands in 2 sheets; jelly-roll; some members can have additional 1-2 strands
characteristic interaction between the domains of this fold allows the formation of five-fold and pseudo six-fold assemblies

Superfamily b.121.2: Group II dsDNA viruses VP [49749] (4 families) duplication: consists of two domains of this fold packed together like the nucleoplasmin subunits
trimeric; in the trimers, the domains are arranged around pseudo six-fold axis
